Prices and Decision Making CHAPTER 6 Prices and Decision Making

Section 1: Prices as Signals Main Idea: Competitive markets and prices are important to capitalism. Objectives: Explain how prices act as signals. Describe the advantages of using prices as a way to allocate economic products. Understand the difficulty of allocating scarce goods and services without using prices.

Section 1 Introduction Life is full of signals that help us make decisions. For example, when we pull up to an intersection, we look to see if the traffic light is green, yellow, or red. We look at the other cars to see if any have their blinkers on, and in this way we receive signals from other drivers regarding their intentions to turn.

Section 1 Introduction (cont.) Doctors even tell us that pain is a signal that something is wrong with our body and may need attention. But have you ever thought about the signals that help us make our everyday economic decisions? It turns out something as simple as a price–the monetary value of a product as established by supply and demand–is a signal that helps us make our economic decisions.

Section 1 Introduction (cont.) Prices communicate information and provide incentives to buyers and sellers. High prices are signals for producers to produce more and for buyers to buy less. Low prices are signals for producers to produce less and for buyers to buy more.

Advantages of Prices Prices are neutral because they do not favor the buyer or the consumer. They are the result of competition. Prices are flexible, allowing for the “shocks” of unforeseen events and changes in the market. Prices have no administration costs. Prices are familiar and easily understood.

Allocations Without Prices Rationing, or the system where the government decides everyone’s “fair” share, leads to the question of fairness. Rationing leads to high administrative costs. Rationing leads to fewer incentives to work and produce.

Prices as a System Together, prices comprise a system that helps buyers and sellers allocate resources between markets, linking all markets in the economy.

Section 2: The Price System at Work Main Idea: Changes in demand and supply cause prices to change. Objectives: Understand how prices are determined in competitive markets. Explain how economic models can be used to predict and explain price changes. Apply the concepts of elasticity to changes in prices.

Section 2 Introduction One of the most appealing features of a competitive market economy is that everyone who participates has a hand in determining prices. This is why economists consider prices to be neutral and impartial. The process of establishing prices is remarkable because buyers and sellers have exactly the opposite hopes and desires.

Introduction (cont.) Buyers want to find good buys at low prices. Sellers hope for high prices and large profits. Neither can get exactly what they want, so some adjustment is necessary to reach a compromise.

The Price Adjustment Process Together, demand and supply make a complete picture of the market. Price adjustments help a competitive market reach market equilibrium, with fairly equal supply and demand.

The Price Adjustment Process (cont.)

The Price Adjustment Process (cont.) Surpluses occur when supply exceeds demand.

The Price Adjustment Process (cont.) Shortages occur when demand exceeds supply.

The Price Adjustment Process (cont.) The equilibrium price is the price at which supply meets demand.

Explaining and Predicting Prices A change in price is normally the result of a change in supply, a change in demand, or both.

Explaining and Predicting Prices (cont.) Even small changes in an inelastic supply can create big changes in price.

Explaining and Predicting Prices (cont.) Elastic supply and demand help keep prices from changing dramatically.

The Competitive Price Theory The theory of competitive pricing represents a set of ideal conditions and outcomes; it serves as a model to measure market performance. In theory, a competitive market allocates resources efficiently. To be competitive, sellers are forced to lower prices, which makes them find ways to keep their costs down. Competition among buyers keeps prices from falling too far.

Section 3: Social Goals vs. Market Efficiency Main Idea: To achieve one or more of its social goals, government sometimes sets prices. Objectives: Describe the consequence of having a fixed price in a market. Explain how loan supports and deficiency payments work. Understand what is meant when “markets talk.”

Section 3 Introduction Chapter 2 examined seven broad economic and social goals that most people seem to share. We also observed that these goals, while commendable, were sometimes in conflict with one another. These goals were also partially responsible for the increased role that government plays in our economy. The goals most compatible with a market economy are freedom, efficiency, full employment, price stability, and economic growth.

Section 3 Introduction (cont.) Attempts to achieve the other two goals—equity and security—usually require policies that distort market outcomes. In other words, we may have to give up a little efficiency and freedom in order to achieve equity and security. Whether this is good or bad often depends on a person’s perspective.

Introduction (cont.) After all, the person who receives a subsidy is more likely to support it however, it is usually wise to evaluate each situation on its own merits, as the benefits of a program may well exceed the costs. What is common to all of these situations, however, is that the outcomes can be achieved only at the cost of interfering with the market.

Introduction (cont.) After all, the person who receives a subsidy is more likely to support it than is the taxpayer who pays for it. In general, it is usually wise to evaluate each situation on its own merits, as the benefits of a program may well exceed the costs. What is common to all of these situations, however, is that the outcomes can be achieved only at the cost of interfering with the market.

Distorting Market Outcomes Achieving equity and security (two of the seven broad economic and social goals) usually requires policies that distort market outcomes. One way to achieve these goals is to set “socially desirable” prices, which interferes with the pricing system. Setting price ceilings affects the allocation of resources. The minimum wage is an example of a price floor.

Distorting Market Outcomes (cont.)

Agricultural Price Supports Government loan support was offered in the 1930s through Commodity Credit Corporation to help stabilize agricultural prices. The CCC loan program led to food surpluses. The CCC switched to deficiency payments, which prevented the government from holding surplus food and had farmers sell their crops on the open market.

Agricultural Price Supports (cont.) In 1996, Congress passed FAIR—Federal Agricultural Improvement and Reform Act. Cash payments replaced price supports and deficiency payments. The payments ended up costing as much. In 2002, farmers will no longer receive any kind of payments.

When Markets Talk Markets “talk” when prices move up or down dramatically. Buyers and sellers respond to changes in the market through their decisions.
